My invention relates toiinproven'ients i11 railroad cross ng 1n which-the rails cross-one another at any angle or-curve, 1110011111110.

tion with double singingfrog members; and the objects of my improvements are, first, toprovide a continuous running'surfacefor car wheels tofrollorer", with clearance for. the flange or the said car wheel to pass through' se'oond,-to afford,facilitiesfor the adgust ment'or renewal ofany-worn'or broken parts independently of the connect ing track-rails leading to the said railroad crossing; and, third to reducethe pound ng ofthe wheels to a minimum as they roll from onerailto the other on the saidcl'ossing at any speed,- and to! revent broken rails or fiat car wheels; 'l 1 a A further object g rm amasisf'to provide a noiseless crossing which inay be manually, mechanically o'rlautoniaticallyoperatedl, 3 7
